Secret plan possessed by Copenhagen, Danish? (6,6)
I believe the answer is:
hidden agenda
'possessed by copenhagen danish?' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'secret plan' is the wordplay.
'secret' becomes 'hidden' (I've seen this before).
'plan' becomes 'agenda' (agenda is a kind of plan).
'hidden'+'agenda'='HIDDEN AGENDA'
Can you help me to learn more?
(Other definitions for hidden agenda that I've seen before include "Secret motive behind one's actions" , "Concealed intentions" , "Sub-text, unstated objective" , "Undisclosed reason" , "Ulterior motive" .)
